Abstract
A gas-liquid catalyzed reaction is performed by introducing at least a portion of the reactive gas into the catalyst as a cross-flow or radial-flow stream. Introducing at least a portion of the reactive gas as a radial flow stream allows the reactive gas to travel through the catalyst bed along a shorter path length. This reduces the pressure drop for the radial flow portion of the gas. The reactive gas can be introduced into the catalyst bed at various heights relative to the height of the catalyst bed.
Claims31
A method for performing a catalyzed gas-liquid reaction, comprising:
- providing a first catalyst bed in a reactor, the reactor including an inner conduit that occupies a portion of the volume of the first catalyst bed and an outer gap between the first catalyst bed and a wall of the reactor, wherein the reactor further comprises a reactor effluent outlet which is fluidly connected to the first catalyst bed;
- exposing a downward axial flow of a hydrocarbon feedstock to a first catalyst located in the first catalyst bed in the presence of a reactive gas under effective processing conditions to produce a first liquid reaction effluent;
- and
- delivering at least a portion of the reactive gas flow into the first catalyst bed via the inner conduit as a radial flow and at least a portion of the reactive gas flows directly into the catalyst bed in a co-current manner with the feedstock, thereby contacting the hydrocarbon feedstock and the first catalyst in the first catalyst bed under first effective processing conditions;
- wherein at least about 50 vol % of the reactive gas flow exits the first catalyst bed by passing into the outer gap, and at least 50 vol % of the first liquid reaction effluent exits the reactor via the reactor effluent outlet.
